    Thank you for your response/interest, Russman. My original post wasn't clear...apologies. My problem is not with the ribbon connector, but with the 4-pin connector that's "servicing" 3 wires...2 white & 1 blue. More specifically, the socket on the DMD board that it plugs into...that socket has broken off the board. Assuming it was a clear "break-off", could the socket just be soldered back on the board? Do I need a new DMD board? A new light engine? How about this...right next to where the 4-pin socket was there is a 3-pin socket that is not being used. Could that 3-pin socket be utilized using some sort of 4-pin to 3-pin adaptor since the 4-pin is only "servicing" 3 wires? Do you know what that 3-pin socket is there for? Thank you, again!!

    When you say it's broken do you mean the small ribbon connector recepticle has fallen down into the DMD shielding? If this is the case you must disassemble the DMD to retrieve that connector and reattach it because trying to solder the ribbon connector to the DMD board probably will not work. Let me know if I can be of help, Russmann.

Okay what you can do is first make sure that you haven't lifted any foil paths on the circuit board. To do this work you will have to remove the dmd board. There are tension springs that have to be taken off to be used for screen centering when reinstalling. Use caution when handling dmd. remove sheild and make sure no small copper foils pulled up from the board. Now if the three wires that are used in the 4-pin plug connector are next to each other then you can use the 3-pin plug connector to reinstall them. Just make sure that they connect to the same place as they were removed from. And in the same order. Also, if you look closely you can see how the wires can be removed from one plug connector and installed in the other without cutting anything. Good luck with this, but you can do it if you have patience, Russmann.

Repair job continued


7. Locate the color wheel cover. It’s got a small green circuit board on top of it with a black/blue wires connected to it. Remove that plug. Also, and this is the trickiest part, remove the two cables coming from the color wheel. One is a copper-colored ribbon cable. That will just slide out easily. The other is a cable with two white and one blue wire. This one is tricky to remove, so you’ll need to ease it out. I pried it out with a jeweler’s screwdriver. DO NOT just pull on the wires.
Note: A reader made the following excellent suggestion to avoid breaking the white connector on the end of the blue/white/white wire:
Having replaced quite a few of these colorwheels as a Samsung service tech, I have found that you do not have to remove the blue/white wire from the DMD board (avoiding the risk of damage to the optical engine) There is enough slack in the wire to route it around the cover when removing it. You can then unplug the wire from the old colorwheel and plug it in the new one (the plastic tab will break off the old connector when you go to remove it,but it will still fit snugly on the new colorwheel) Using this method I have had no problems reusing the old connecting cable

Color wheel cover view from top-down. This part has three screws and slides straight up.
color-wheel-wires.jpg 8. Unscrew the color wheel cover. There are three screws holding it in place. One to the rear of the set, and two in front. The one to the rear is tucked way in, so I just unscrewed them and carefully left them in place and pulled them out with the cover. Slide the cover straight up, exposing the color wheel. As you do, note where the color wheel wires go — out the gap in the front.
cover-removal.jpg 9. Remove the bad color wheel. The color wheel is held in place with three screws. Remove the screws and the color wheel. The color wheel may be stuck in place with the foam tape, but that’ll give with a small tug. To remove the wheel cleanly, I lifted the front edge and slid it toward the front.
color-wheel.jpg 10. Insert the new colorwheel. It can be tricky to do this without touching the wheel, or bumping the wheel into the case. (This is where you need the nerves of steel). Once you get the proper angle, it will slide into place. Don’t force it — remember, this thing needs to spin at 9000 RPM, it’s probably pretty sensitive. At first, I tried to put it in place with the screws already in the holes. This didn’t allow me to slide it in properly. Lesson learned: put it in without the screws and then hold the screws in place with tweezers, if necessary.
11. Put the color wheel cover back on with the wires out the space facing the front of the case. Make sure the wires reach their destinations, and screw in the cover. Three screws. Attach the three connectors. The metal contacts on the ribbon cable face the rear.
12. Put all the guts back in place. Slide the center unit back in. Without touching the projector lens, open up the slice in the foam so it wraps around the projector lens, and slide it in the rest of the way. The center unit can only go in on it’s track, so again, don’t force anything. Connect the two wires you removed on the left side. They should only go in one way. Did I mention don’t force anything? Screw the sensor switch onto the bracket on the right.
13. Put the power cable in it’s slot. Just the way you noted on the way out.
14. Slide the left PC board and panel back in place. There are two screws that hold it in place that you screw in now, the rest hold on the access panel.
15. Put the projector lamp back in place and screw it into place. I forgot to do this both times.
16. Put the access panel back on and screw it in (14 screws)
17. Plug in the television, say a prayer, and turn it on.

Picture is black and white and fleckers. changed


In most cases this is due to the fact that the color wheel has shattered into pieces and will need to be replaced. Replacing the color wheel is not too easy, but if you are technically handy it isn't that tough to replace either. The part number for the color wheel is BP96-00250A and will run between 80-130 dollars for the part.

My samsung dlp tv model#hln617w keeps turning off. Only stays on for 2 minutes. I replaced fan #2. Thunking that was the problem.


Why did you replace the fan was it noisey and did that cure the noise. These sets commonly have problems with color wheels-do you get motor noise at startup?

What does the color wheel "plug in" to?


the white clip that the 2 white/1 blue wire plugs into breaks when you remove the the wire. This should not be a problem as the wire should still fit snug when you plug back in.

Color wheel/ Samsung


The Color Wheel (part# BP96-00674A) will run you just under $100 from www.samsungparts.com and they offer a variety of shipping methods which will increase your total amount spent. I just received mine today and I ordered it this past Sunday night. My HLR6167W started buzzing and gave me a black and white picture that morning and I was all over the internet investigating the symptom. I elected to go with the color wheel based on what I was seeing and all the different things I read up on. I plan on putting it in tonight and will let you know the difficulty surrounding its installation when I am done.
